1t appertaius to make and use the seine.

his invention relates to harvesters end the like, and particularly to that type which is provided with oii'set working elements, each adapted to follow one behind the other, to work upon on eree adjacent that which is Worked upon by the preceding element. Heretofore in such machines the oiiset ports have been rigidly connected, or else menuelly operable steering devices were necessery to cause said ofi'set parts to retain their relative positions when the machine was.

making a turn. It-is obvious that e plurality of oflset, loosely, connected cutting ele ments of e harvester, when making a turn, would tend to follow behind the preceding drawing force in' the shortest possible path. The cutting elements would therefore cut corners and a quantity of grain would be left standing at each corner. Even in cases therefore, where the elements have been held in offset relation, some manually operable steering means was necessary in connection with each element to prevent it from so cutting corners.

The object of this inventionlis to provide a harvester or the like in which the working elements are automatically guided, oil side, in such positions that each element will cut its full swath without the engine or any part of the mechanism going into the standing grain, this condition being .true even when the harvester is making a turn.

Broadly, the invention consists in providing in addition to a motion transmitting interconnection between the several elements, a mechanism comprising a steering truck carried b one element and operated by connections tween said truck and the preceding olement,sueh that when the preceding drawing, but

to one,

element is deflected from its course, the followin element will be automatically defiected from its course. Consequently, the preceding element in traveling in any course Whatever will direct the following element in a course, which is always substantially parallel to the course taken by said preceding element,

To illustrate the invention, machine has been used for an it is obvious that the invention e harvesting example, but 1s applicable in all cases where offset working parts are vused, snch es in plows, similar devices. 4

A. harvesting machine embodying the invention is depicted in the accompanying various modifications may be made, without departing from the spirit or scope of the invention.

In the draWingz-Figure l is a plan view of a, portion'of it harvesting machine embodying the invention; Fi 2 is e detail view showing the manner oi connecting the draw cable to the working elements.

in these views, like reference Characters refer to corresponding parts.

The engine for drawing the working ele;

ments not forming any part of the inven tion, has been omitted, such an engine is shown at 1. Two working elements are shown whose frames are formed by the recteng'nhirly disposed elements, 20, 21, 22 and 23. Obviously, any number of such elements might be used and each element might be of any construction whatsoever. These elements are connected to the drew her 1 of the engine at (i, preferably by a drew cable the portions of rollers, barrows and i 4 Q which, between the working iements, being preferebiy independentsectlons looped together or otherwise connected, as shown clearly inFi 2. "ii nortion of the cable in advance or wo'r element is rigidly connected to the some menner, such as by the clamp 18 secured to the front member 20 of each element. The cable is prefersbly first doubled back upon itself to form a. loop and then said loop secured to the clamp. A loop is formed in the following cable portion which is linked with said first loop, es further shown by but the drew her of F any convenient alt] element frames,
